the lighting on the night version bothers me somewhat, I think its due to the weak overlighting, obviously night is dark, but your image is so blue that i feel its missing a bit stronger moon lighting presence.

Just a thought though, both pieces are textured well. Love the comp too.

Edit: Is there a bump on the wall at all? It doesn’t look like it and with such a strong overhead light, that would really give the wall an awesome presence. (if there is, bump it up a bit… see what i did there…ya… ya, i made a bad pun.)
